Question

At the instant of the figure, a 2.0 kgparticle P has a
position vector r ofmagnitude 2.4 m and
angleθ1 = 45° and a velocity
vectorv of magnitude 4.5m/s and angle
θ2 = 30°. ForceF of magnitude
1.3 Nand angle θ3 = 30° acts onP. All
three vectors lie in the xy plane.

(a) What is the angular momentum of theparticle
about the origin?
kg·m2/s
